摘要： A profile of a finished part is recognized based on an inputted CAD data. A delta volume for the finished part is decomposed based on information on cutting tools and the profile. Thereafter, a dependency graph representing precedence relation between the decomposed delta volumes is generated. And then, a process sequence graph representing process plans is generated based on the dependency graph. The delta volume decomposition is performed based on information on cutting tools and a machine configuration as well as part geometry, such that the decomposed delta volumes are suitable to be cut away from a raw stock by the cutting tools.

摘要： A method for automatically generating a part program for use in a STEP-NC (STEP-Compliant Data Interface for Numerical Controls) controller in a SFP (shop-floor programming) system based on an ISO 14649 data model is provided. First, geometric kernel data is generated by interpreting a STEP physical file or an ISO 14649 part program. Then, manufacturing features are recognized from the geometric kernel data and a process plan according to the ISO 14649 is established. Thereafter, the process plan is edited and an ISO 14649 part program is generated. Subsequently, a tool path is created based on manufacturing feature information specified in the ISO 14649 part program and the produced tool path is verified in a CNC (computer-based numerical control) apparatus. By including functions of a CAD/CAPP/CAM system, the present invention makes it possible to readily generate a part program for use in the STEP-NC on the CNC controller.

摘要： A STEP(standard for the exchange of product data model)-NC(numerical control) system having a function of a non-linear process plan includes a non-linear process plan generator and a machine tool. The non-linear process plan generator produces a non-linear process plan including alternative machining process plans, and creates a part program including information of the non-linear process plan. The machine tool loads therein the part program created by the non-linear process plan generator and extracts the information of the non-linear process plan by analyzing the part program. The machine tool machines a workpiece based on the information of the non-linear process plan to manufacture a desired product.

摘要： An intelligent STEP-NC (Standard for the Exchange of Product model-Numerical Controller) overcomes shortcomings of conventional NCs with a closed structure. The intelligent STEP-NC intelligently performs a machining process based on ISO 14649 data while autonomously coping with an emergency at a shop-floor. Thus, the discontinuity of information in a CAD-CAM-CNC chain where the current NCs are operated can be overcome and the concept of "design-to-manufacture" can be realized.
